Seawater intrusion barrier
WebThe construction of subsurface physical barriers is one of various methods used to control seawater intrusion (SWI) in coastal aquifers. This study proposes the mixed physical … WebCurrent water abstractions lead to salt water intrusion near the water intake at approximately 10% of the time. The model indicates that an additional water abstraction of 5 m 3 /s will lead to an increase in salt water reaching the intake at 10% of the time.
